      • Worked on the project SEARCCH that is a community-driven platform to aid researchers to share and reuse experimental artifacts in the cybersecurity domain and the project is supported by the National Science Foundation. • Automated the process of collecting data and files related to artifacts from the URL provided by the user. This data is further processed and stored in the database using sqlalchemy. Reduced the need of manual data entry for 85 percent of artifacts. • Constructed a markdown parser to convert markdown text to an abstract syntax tree and parse it to collect data that was missed initially during data extraction. Improved Metadata for 20 percent of all artifacts and 67 percent of GitHub artifacts. • Keywords improve the quality of search so identifying relevant keywords automatically was necessary for the hub. • Built a keyword extractor to get keywords automatically from the publication pdf of the experimental artifacts using Text Rank Algorithm thus adding meaningful keywords as metadata for nearly 70 percent of the artifacts. • Improvised keyword extraction for 60 percent of code artifacts by extracting comments, names of class, methods, and attributes from the source code files and processing further depending on the parts of speech of these words.
