Preamble to the description
The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD [001] The disclosure herein generally relates to event creation, and, more particularly, to a method and system for creating events using historical event information.
BACKGROUND [002] As digitalization has become popular, now creating events (for example, a sourcing event) can be done easily using digital devices. However, this process is not fully automated, yet. A user who is handling a system for creating events still needs to put some manual efforts. For example, the user needs to make sure that data such as but not limited to information about the type of event to be created, questionnaire data required from suppliers, set of items to be sourced, and appropriate industry/organization approved suppliers from market to be invited for the sourcing event, and so on are available, which are inputs required for event creation. Further, even after creating an event, the user/organizer may have to put additional efforts for finding suitable suppliers who can organize the event.
SUMMARY [003] Embodiments of the present disclosure present technological improvements as solutions to one or more of the above-mentioned technical problems recognized by the inventors in conventional systems. For example, in one embodiment, a processor implemented method for event recommendation is provided. In this method, an event title is received as input, via one or more hardware processors. Further, a vector representation of the received event title is generated, via the one or more hardware processors. Further, the vector representation of the event title is compared with a plurality of historic event titles, using a data model, via the one or more hardware processors. While comparing the vector representation of the event title with that of the historic event titles, initially a coefficient value for each of the plurality of historic event titles in comparison with the event title received as input is generated, using a coefficient-based voting algorithm, by calculating a plurality of distance values, between the generated

vector representation of the received event title and a vector representation of the historic event title, using a plurality of distance calculation techniques, and then by multiplying each of the plurality of distance values with a unique weightage score of corresponding distance calculation technique. After generating the coefficient value, the plurality of historic event titles are ranked based on the generated coefficient value of each of the plurality of historic event titles. Further, a pre-defined number of historic event titles having highest value of the coefficient value from among the plurality of historic event titles are recommended via the one or more hardware processors.
[004] In another aspect, a system for event recommendation is provided. The system includes one or more hardware processors, a communication interface, and a memory storing a plurality of instructions. The plurality of instructions when executed cause the one or more hardware processors to receive an event title is received as input. Further, a vector representation of the received event title is generated, via the one or more hardware processors. Further, the vector representation of the event title is compared with a plurality of historic event titles, using a data model, via the one or more hardware processors. While comparing the vector representation of the event title with that of the historic event titles, initially a coefficient value for each of the plurality of historic event titles in comparison with the event title received as input is generated, using a coefficient-based voting algorithm, by calculating a plurality of distance values, between the generated vector representation of the received event title and a vector representation of the historic event title, using a plurality of distance calculation techniques, and then by multiplying each of the plurality of distance values with a unique weightage score of corresponding distance calculation technique. After generating the coefficient value, the plurality of historic event titles are ranked based on the generated coefficient value of each of the plurality of historic event titles. Further, a pre-defined number of historic event titles having highest value of the coefficient value from among the plurality of historic event titles are recommended via the one or more hardware processors.

Further, the vector representation of the event title is compared with a plurality of historic event titles, using a data model, via the one or more hardware processors. While comparing the vector representation of the event title with that of the historic event titles, initially a coefficient value for each of the plurality of historic event titles in comparison with the event title received as input is generated, using a coefficient-based voting algorithm, by calculating a plurality of distance values, between the generated vector representation of the received event title and a vector representation of the historic event title, using a plurality of distance calculation techniques, and then by multiplying each of the plurality of distance values with a unique weightage score of corresponding distance calculation technique. After generating the coefficient value, the plurality of historic event titles are ranked based on the generated coefficient value of each of the plurality of historic event titles.

Among other capabilities, the processor(s) are configured to fetch and execute computer-readable instructions stored in the memory. In an embodiment, the system 100 can be implemented in a variety of computing systems, such as laptop computers, notebooks, hand-held devices, workstations, mainframe computers, servers, a network cloud and the like.
[015] The communication interface(s) 103 can include a variety of software and hardware interfaces, for example, a web interface, a graphical user interface, and the like and can facilitate multiple communications within a wide variety of networks N/W and protocol types, including wired networks, for example, LAN, cable, etc., and wireless networks, such as WLAN, cellular, or satellite. In an embodiment, the communication interface(s) 103 can include one or more ports for connecting a number of devices to one another or to another server.
[016] The memory 101 may include any computer-readable medium known in the art including, for example, volatile memory, such as static random access memory (SRAM) and dynamic random access memory (DRAM), and/or non-volatile memory, such as read only memory (ROM), erasable programmable ROM, flash memories, hard disks, optical disks, and magnetic tapes. In an embodiment, one or more components (not shown) of the system 100 can be stored in the memory 101. The memory 101 is configured to store a plurality of operational instructions (or ‘instructions’) which when executed cause one or more of the hardware processor(s) 102 to perform various actions associated with the event recommendation being performed by the system 100. The system 100 can be implemented in a variety of ways as per requirements. Various steps involved in the process of event recommendation being performed by the system 100 are

explained with description of FIGS. 2, 3, and 4. All the steps in FIGS. 2, 3, and 4 are explained with reference to the system of FIG. 1.
[017] FIG. 2 is a flow diagram depicting steps involved in the process of generating event recommendations using the system of FIG. 1, according to some embodiments of the present disclosure. In order to create an event, a user of the system 100 can initially decide a suitable event title that matches / indicates one or more characteristics of the event being planned. The user then inputs the decided title to the system 100 using a suitable user interface.
[018] At step 202, the system 100 receives/collects the event title entered by the user as input. The system 100 may then do some standard pre-processing to interpret the collected input. Further, at step 204, the system 100 generates a vector representation of the event title.
[019] For any given event title, the system 100 generates the vector representation by executing the following steps:
• Remove stop words from the event titles to generate corresponding ‘clean titles’
• Identify unique words from the clean titles
• Calculated the IDF (Inverse Document Frequency) of all the unique words
• Calculated the TF (Term Frequency) of each unique word
• Calculate d TF*IDF to form the word vectors
[020] This process is now explained by taking an example:
[021] For example, consider that a training document set contains two documents d1 and d2, and a test document set contains two other documents d3 and d4.
Train Document Set:
d1: Event IT Hardware
d2: Event Laptop premium standard Test Document Set:
d3: Event Electrical equipment
d4: Event Laptop premium moderate standard

[022] Vectorization is done for the test dataset based on the documents in the training data set. Initially the system 100 removes all the stop words from the titles from each of documents, to generate the clean titles. The system 100 then identifies and extracts unique words from the titles. For the test and training data sets, the unique words extracted by the system are:
[Event , IT ,Hardware, Laptop, Premium, Standard]
[023] The system 100 then calculates an Inverse Document Frequency (IDF) for each of the unique words, as:

Where,
df(d,t) represents frequency of the term, and ‘n' is number of documents in which the term is present [024] With some example values given, consider that the IDF values calculated for each of the unique words is as given below: Event – 1 IT – 2.09 Hardware – 2.09 Laptop – 1.40 Premium – 1.40 Standard – 1.40 [025] Based on the calculated IDF values, an IDF vector is generated by the system 100, and is represented as = (1 2.09 2.09 1.40 1.40 1.40). [026] The IDF values may be represented in a matrix form as: [[1,0,0,0,0,0], [0,2.09,0,0,0,0], [0,0,0,2.09 ,0,0], [0,0,0,1.40,0,0], [0,0,0,0,1.40,0], [0,0,0,0,0,1.40]] Where, in the matrix form, the values are in the order:
[Event , IT ,Hardware, Laptop, premium, standard]

[027] The system 100 then calculates a Term Frequency (TF) vector as:
Tf vector = [[1,0,0,0,0,0],[1,0,0,1,0,1]] [028] Where, TF is number of times a word appears in a document divided by the total number of words in the document.
[029] The system 100 then calculates value of Tf-Idf as:
Tf-Idf ij = TF i,j * log(1+n/(1+dfi ))+1 --- (2)
[030] Using equation (2), the value of Tf-Idf is calculated for the above referenced values as: Tf-Idf =
[[1,0,0,0,0,0],[1,0,0,1,0,1]] * [[1,0,0,0,0,0], [0,2.09,0,0,0,0], [0,0,0,2.09 ,0,0], [0,0,0,1.40,0,0], [0,0,0,0,1.40,0], [0,0,0,0,0,1.40]]
= [[1 0 0 0 0 0] [1 0 0 1.4 0 1.4]]
[031] The system 100 then performs l2 normalization on the calculated Tf-Idf value to generate the vector representation as equal to: [[1 0 0 0 0 0] [0.33 0 0 0.66 0 0.66]] [032] The system 100 stores in a data repository in the memory 101, details of a plurality of historical event titles, each representing a historical/past event, along with details of each of the events. The ‘details’ of the event may include information such as but not limited to time stamp of the event, number of participants, supplier/organizer of each event, cost of the event, and so on. The historic event titles and details may be automatically fetched from any external sources or may be manually entered to the system 100 using a suitable interface provided.

[033] At step 206, the system 100 compares the vector representation of the event title with vector representation of each of the historic event titles. In an embodiment, the vector representations of the plurality of historic event titles are generated dynamically each time an input data is collected and processed by the system 100. In another embodiment, the vector representations of all the historical event titles are generated once and are stored in the database. When the vector representations of the historic event titles are to be compared with the vector representation of the input data, the system 100 fetches the vector representations from the database. Steps involved in the process of comparing the vector representations of the input event title and the vector representations of the historic event titles are depicted in FIG. 3.
[034] At step 302, the system 100 generates a coefficient value for each of the historic event titles, using a coefficient voting algorithm. At this step, the system 100 may use a plurality of suitable techniques (Natural Language Processing (NLP), and Word Processing (WP) techniques) to calculate distance between the vector representation of the input event title and each of the historic event titles. A few examples of techniques that may be used for calculating the distance are Word Mover’s distance, Classic Cosine similarity, Global Vectors for Word representation (GloVe),and Siamese Manhattan LSTM (SMLSTM). In an embodiment, a selected number of such techniques are pre-configured with the system 100 for automatic execution. In another embodiment, the system 100 may prompt the user to make a selection of one or more of the techniques, using a suitable user interface. Each of the techniques is assigned a unique weightage score. The system 100 multiplies the distance values calculated by each technique with the corresponding weightage of each of the techniques to generate the coefficient value. In an embodiment, the weightage score of each of the techniques (in turn the combination of weightage scores of all the techniques used) is determined during training of a machine learning data model being used by the system 100 for processing the input data received.
[035] Further, at step 304, the system 100 ranks each of the plurality of historic event titles, based on the coefficient value. After ranking the plurality of

historic event titles, the system 100, at step 306, selects a pre-defined number of historic event titles having highest coefficient value among the plurality of historic event titles. The system 100 may then recommend the selected pre-defined number of historic event titles to the user, at step 208. The system 100 also provides option for the user to access details of each of the historic/past events represented by each of the recommended historic event titles.
[036] Along with the historic event title suggestion, the system 100 also recommends one or more suppliers who can handle the event being planned by the user, and an estimated event duration, which the user may consider while planning the event.
[037] In order to recommend the one or more suppliers, the system 100 identifies a plurality of suppliers of the recommended pre-defined number of historic event titles. Further, for each of the plurality of suppliers, the system 100 generates a weighted average score based on a determined similarity of corresponding historic event titles (which may be represented by the assigned ranking of each of the historical evet titles) with the input event title, and values of a plurality of configurable attributes. Further, based on the suppliers having the highest value of the weighted average score, the system 100 generates recommendation of the one or more suppliers.
[038] In order to estimate the event duration, the system 100 identifying a supplier who has been shortlisted by the user. The shortlisted supplier may or may not be from the recommendations generated by the system 100. Once the supplier is identified, the system 100 identifies a plurality of events organized by the shortlisted supplier. The system 100 then applies a multiple linear regression model on the identified plurality of events to determine a tentative event duration.
[039] The user may use the recommendations (historic event titles, suppliers, and the estimated event duration) to generate the event / further plan the event. The system 100 may provide an option for the user to make modifications to any of the historic events, as per requirements of the task being planned.
[040] FIG. 4 is a flow diagram depicting steps involved in the process of training a machine learning model for selecting a set of historic event titles from a

plurality of historic event titles, to generate the event recommendation using the system of FIG. 1, in accordance with some embodiments of the present disclosure. The system 100 uses the machine learning model to process the input event title, using the steps in FIG. 2 and FIG. 3 to generate the recommendations. The machine learning model is initially trained using data pertaining to the historic/past events, using the steps in method 400. Steps in method 400 are almost identical to the steps in method 200 and 300. However while generating/training the machine learning data model, the system 100 uses a plurality of combinations of weightage values for the techniques being considered, and determines/identifies a combination of weightages for which accuracy of the machine learning data model is closest to a pre-defined accuracy benchmark. The predictions generated by the system 100 for each input provided, are one of the inputs for training and updating the machine learning data model. In an embodiment, in addition to the predictions generated, the system 100 may collect information on data such as but not limited to historic event title(s), supplier(s), and event duration selected/opted by the user, and use the collected data for training the machine learning data model.
Use-case scenario/Example:
[041] Consider that a user is trying to create an event for Request for Proposal (RFP)/auction. Training data (i.e. historical sourcing data, in this context), used by the system 100 for training the machine learning model is given in Table. 1.

Table. 1 [042] Consider that the techniques used for processing the training data are Word Mover’s Distance, Classic Cosine Similarity, GloVe, and MaLSTM. Each of these techniques is assigned an initial weightage of 0.25, and the machine learning model is generated/built. While generating the predictions, the system 100 is configured to use a combination of weightages assigned to the selected techniques. Example of weightage combinations are given in Table. 2.

Table. 2
[043] Consider that the input event title to the system 100 is “Event for top-end laptop sourcing”. This event title is referred to as “test event title”.
[044] From the training data, the top n (wherein in this example, value of ‘n’ is considered as 3) best matching event titles are conformed as accuracy benchmark to be:
• Event for Laptop of premium standard
• High Configuration Laptop Sourcing Event
• Bulk Laptop Order with standard configuration
[045] The test event title is pre-processed using the NLP techniques and corresponding vector representation is generated. The system 100 then uses the machine learning data model to find the top 3 best matching historical event titles

using each of the techniques. Consider that the results returned by each of the techniques are as in Table. 3.

Table. 3 [046] Further the system 100 uses a majority voting algorithm ‘X’ to mine out an ensemble prediction from the table. 2 as:
• High Configuration Laptop Sourcing Event
• Event for Laptop of premium standard
• Bulk Laptop Order with standard configuration
[047] The system 100 further generates the coefficient value for each of the historic event titles using the Voting Algorithm. The voting algorithm multiplies a distance value calculated by each technique with the corresponding weightages assigned to the technique in each iteration to derive the coefficient value. The system 100 further sorts the historic event titles based on the generated coefficient value of each of the historic event titles. Further, ‘n’ historic event titles having highest coefficient values are identified as the ‘predictions’ by the system 100.

[048] This process is reiterated for all the weightage combinations present in table 2.0 and ensemble prediction results are stored and matched with an accuracy benchmark. The first combination of weightages for which the ensemble prediction results matches with the accuracy benchmark, iteration is stopped and the model is finalized for the test data.
[049] This process is repeated for different training data, to generate/ fine-tune/update the machine learning data model for finding the best matching event title. During this process, the system 100 may identify most occurring combination of weightages, which in turn may be used by the system for building a final version of the machine learning data model.

historic event titles and values of a plurality of configurable attributes related to the event title received as input; and generating recommendation of one or more of the identified plurality of suppliers, based on the generated weighted average score.
5. The method as claimed in claim 3, wherein recommending the event
duration comprises:
identifying shortlisted supplier;
identifying a plurality of events organized by the shortlisted
supplier; and
applying a multiple linear regression model on the identified
plurality of events to determine a tentative event duration.
6. A system for event recommendation, comprising:
one or more hardware processors (102);
a communication interface (103); and
a memory (101) storing a plurality of instructions, the plurality of
instructions when executed cause the one or more hardware
processors to:
receive an event title as input;
generate a vector representation of the received event title;
compare the vector representation of the event title with a
plurality of historic event titles, using a data model,
comprising:
generating a coefficient value for each of the plurality of historic event titles in comparison with the event title received as input, using a coefficient-based voting algorithm, wherein generating the coefficient value for each of the plurality of historic event titles comprises:

calculating a plurality of distance values, between the generated vector representation of the received event title and a vector representation of the historic event title, using a plurality of distance calculation techniques; and
multiplying each of the plurality of distance
values with a unique weightage score of
corresponding distance calculation
technique; and
ranking the plurality of historic event titles based on the
generated coefficient value of each of the plurality of historic
event titles; and
recommend a pre-defined number of historic event titles having highest value of the coefficient value, from among the plurality of historic event titles.
7. The system as claimed in claim 6, wherein the system generates the data model by:
iteratively assigning a plurality of unique combinations of
weightages to a set of a plurality of word processing(WP) techniques
and a plurality of natural language processing(NLP) techniques;
determining distance value for each of the plurality of historic event
titles, using each of the plurality of WP and NLP techniques, for
each unique combination of weightages assigned;
deriving the coefficient value from each of the distance values, based
on the assigned unique combination of weightages;
ordering the plurality of historic event titles based on the coefficient
value;
selecting one or more of the plurality of historic event titles, based
on the coefficient value, as predictions;

determining accuracy of the predictions, generated for each unique
combination of weightages;
selecting predictions for which the determined accuracy is at least
equal to a defined accuracy benchmark; and
training a machine learning data model using the selected
predictions for which the determined accuracy is at least equal to a
defined accuracy benchmark.
8. The system as claimed in claim 6, wherein recommending the pre-defined number of historic event titles comprises recommending one or more suppliers and an event duration, for the event.
9. The system as claimed in claim 8, wherein the system recommends the one or more suppliers by:
identifying a plurality of suppliers of the recommended pre-defined
number of historic event titles;
generating a weighted average score for each of the plurality of
suppliers, based on the determined similarity of corresponding
historic event titles and values of a plurality of configurable
attributes; and
generating recommendation of one or more of the identified plurality
of suppliers, based on the generated weighted average score.
10. The system as claimed in claim 8, wherein the system recommends the event
duration by:
identifying shortlisted supplier;
identifying a plurality of events organized by the shortlisted
supplier; and
applying a multiple linear regression model on the identified
plurality of events to determine a tentative event duration.
