Sangrahaka: a tool for annotating and querying knowledge graphs

Hrishikesh Terdalkar, Arnab Bhattacharya

Abstract

We present a web-based tool Sangrahaka for annotating entities and relationships from text corpora towards construction of a knowledge graph and subsequent querying using templatized natural language questions. The application is language and corpus agnostic, but can be tuned for specific needs of a language or a corpus. The application is freely available for download and installation. Besides having a user-friendly interface, it is fast, supports customization, and is fault tolerant on both client and server side. It outperforms other annotation tools in an objective evaluation metric. The framework has been successfully used in two annotation tasks. The code is available from https://github.com/hrishikeshrt/sangrahaka.
