Abstract:
This notebook details the participation of the University of Massachusetts Amherst in the Cumulative Citation Recommendation task CCR of the TREC 2012 Knowledge Base Acceleration Track. UMass objective is to introduce a single model for Knowledge Base Entity Linking and Knowledge Base Acceleration stream filtering using bi-directional linkability between knowledge base KB entries and mentions of the entities in documents. Our system focuses on estimating linkability between documents and Knowledge Base entities which measures compatibility in two directions 1 from a KB entity to documents and 2 from mentions of entities in documents to their KB entries. The entity to document direction, is modeled as a retrieval task where the goal is to identify the most relevant documents for an entity in the evaluation time range. However, if the entity is ambiguous, the retrieved documents may contain documents that are relevant to other entities with the same or similar name. To address this, we want to leverage information from the document to disambiguate the entity. We observe that this problem, from mention to KB entity, is very similar to the TAC Knowledge Base Population Entity Linking Task Ji et al., 2011. The major goal of our participation is to explore how these two directions, from KB to documents and back can be combined.
