Entity Set Expansion using Topic information
This paper proposes three modules based on latent topics of documents for alleviating “semantic drift” in bootstrapping entity set expansion. These new modules are added to a discriminative bootstrapping algorithm to realize topic feature generation, negative example selection and entity candidate pruning. In this study, we model latent topics with LDA (Latent Dirichlet Allocation) in an unsupe...
متن کاملEntity Set Expansion using Interactive Topic Information
We propose a newmethod for entity set expansion that achieves highly accurate extraction by suppressing the effect of semantic drift; it requires a small amount of interactive information. We supplement interactive information to re-train the topic models (based on interactive Unigram Mixtures) not only the contextual information. Although the topic information extracted from an unsupervised co...
متن کاملA Probabilistic Co-Bootstrapping Method for Entity Set Expansion
Entity Set Expansion (ESE) aims at automatically acquiring instances of a specific target category. Unfortunately, traditional ESE methods usually have the expansion boundary problem and the semantic drift problem. To resolve the above two problems, this paper proposes a probabilistic Co-Bootstrapping method, which can accurately determine the expansion boundary using both the positive and the ...
متن کاملEntity List Completion Using Set Expansion Techniques
Set expansion refers to expanding a partial set of “seed” objects into a more complete set. In this paper, we focus on relation and list extraction techniques to perform Entity List Completion task through a two stage retrieval process. First stage takes given query entity and target entity examples as seeds and does set expansion. In second stage, only those candidates who have valid URI in Bi...
متن کاملBootstrapping for Named Entity Tagging Using Concept-based Seeds
A novel bootstrapping approach to Named Entity (NE)tagging using concept-based seeds and successive learners is presented. This approach only requires a few common noun or pronoun seeds that correspond to the concept for the targeted NE, e.g. he/she/man/woman for PERSON NE. The bootstrapping procedure is implemented as training two successive learners. First, decision list is used to learn the ...
