ARPANI@BIT_DURG: KBP English Slot-filling Task Challenge

The present communication laid by the above mentioned TAC-SF Track participants aims to report TAC forum about the system-incorporated towards Slot-Filling task. Given a list of PER / ORG relevant attributes, the task aimed at extracting Noun-phrases that fit as assigned values to these attributes, as narrated either in one or more relevant pools of newswires or described as declarative and / or factual information in supporting knowledge-base. For accomplishing above, care was taken to identify such slot-fill patterns from every instance of relevant context whether in newswire or knowledge-base. Hence, the system relied upon generating exhaustive supporting vocabulary patterns that associate with desired slot-patterns in semantic sense. Three different kinds of sources were used to build entity-relevant vocabulary in the Task Challenge so as to search for the precise information about the entity-attributes (may be single-valued or multiple valued) mentioned in Slot-fill track task definition. The team’s spirits feels elevated at the thought of using the free text from the Wikipedia pages associated with the knowledge base nodes, while building the evaluation model as it adds to the robustness and reliability of the system even at the time of inaccessibility of the Web.
