Riloff, Ellen M. | Domain-specific coreference resolution with lexicalized features | Most coreference resolvers rely heavily on string matching, syntactic properties, and semantic attributes of words, but they lack the ability to make decisions based on individual words. In this paper, we explore the benefits of lexicalized features in the setting of domain-specific coreference reso... | 2014-01-01 | |

Riloff, Ellen M. | Learning domain-specific information extraction patterns from the web | Many information extraction (IE) systems rely on manually annotated training data to learn patterns or rules for extracting information about events. Manually annotating data is expensive, however, and a new data set must be annotated for each domain. So most IE training sets are relatively small. C... | Information extraction; Domain-specific; Annotated training sets; MUC-4 | 2006 |

Riloff, Ellen M. | Learning subjective nouns using extraction pattern bootstrapping | We explore the idea of creating a subjectivity classifier that uses lists of subjective nouns learned by bootstrapping algorithms. The goal of our research is to develop a system that can distinguish subjective sentences from objective sentences. First, we use two bootstrapping algorithms that explo... | Subjective nouns; Bootstrapping; Extraction patterns; Subjectivity classifier; Naive Bayes classifier | 2003 |

Riloff, Ellen M. | Conundrums in noun phrase coreference resolution: making sense of the state-of-the-art | We aim to shed light on the state-of-the-art in NP coreference resolution by teasing apart the differences in the MUC and ACE task definitions, the assumptions made in evaluation methodologies, and inherent differences in text corpora. First, we examine three subproblems that play a role in coref... | Noun phrase; Coreference resolution; MUC; ACE | 2009 |

Riloff, Ellen M. | Bootstrapping method for learning semantic lexicons using extraction pattern contexts | This paper describes a bootstrapping algorithm called Basilisk that learns high-quality semantic lexicons for multiple categories. Basilisk begins with an unannotated corpus and seed words for each semantic category, which are then bootstrapped to learn new words for each category. Basilisk hypothe... | Basilisk; Bootstrapping method; Semantic lexicons | 2002 |

Riloff, Ellen M. | Corpus-based identification of non-anaphoric noun phrases | Coreference resolution involves finding antecedents for anaphoric discourse entities, such as definite noun phrases. But many definite noun phrases are not anaphoric because their meaning can be understood from general world knowledge (e.g., "the White House" or "the news media"). We have develope... | Corpus-based identification; Non-anaphoric noun phrases; Coreference resolution; MUC-4; Discourse entity; DE | 1999 |

Riloff, Ellen M. | Identifying sources of opinions with conditional random fields and extraction patterns | Recent systems have been developed for sentiment classification, opinion recognition, and opinion analysis (e.g., detecting polarity and strength). We pursue another aspect of opinion analysis: identifying the sources of opinions, emotions, and sentiments. We view this problem as an information ext... | Sentiment classification; Opinion recognition; Opinion analysis; Conditional random fields; AutoSlog; Sources of opinions | 2005 |

Riloff, Ellen M. | Unsupervised learning of contextual role knowledge for coreference resolution | We present a coreference resolver called BABAR that uses contextual role knowledge to evaluate possible antecedents for an anaphor. BABAR uses information extraction patterns to identify contextual roles and creates four contextual role knowledge sources using unsupervised learning. These knowledge ... | Coreference resolution; Coreference resolver; BABAR; Contextual role knowledge; Unsupervised learning | 2004 |

Riloff, Ellen M. | Corpus-based bootstrapping algorithm for semi-automated semantic lexicon construction | Many applications need a lexicon that represents semantic information but acquiring lexical information is time consuming. We present a corpus-based bootstrapping algorithm that assists users in creating domain-specifi c semantic lexicons quickly. Our algorithm uses a representative text corpus for ... | Bootstrapping algorithm; Lexicon construction | 1999-06 |

Hanna, Patricia Lee | Summaries and comments on Lappin, S. Sorts, ontology and metaphor: the semantics of sortal structure | In this interesting study, Shalom Lappin argues that any adequate theory of sortal incorrectness must meet four requirements. First, it must account for the truth valuelessness of sortally incorrect sentences. Second, it must provide a means of distinguishing truth valuelessness arising from sortal... | Valuelessness; Incorrectness | 1983 |

Riloff, Ellen M. | Exploiting strong syntactic heuristics and co-training to learn semantic lexicons | We present a bootstrapping method that uses strong syntactic heuristics to learn semantic lexicons. The three sources of information are appositives, compound nouns, and ISA clauses. We apply heuristics to these syntactic structures, embed them in a bootstrapping architecture, and combine them with... | Syntactic heuristics; Semantic lexicons; Bootstrapping method; Appositives; Compound nouns; ISA clauses; Co-training | 2002 |

Riloff, Ellen M. | Unified model of phrasal and sentential evidence for information extraction | Information Extraction (IE) systems that extract role fillers for events typically look at the local context surrounding a phrase when deciding whether to extract it. Often, however, role fillers occur in clauses that are not directly linked to an event word. We present a new model for event extract... | Information extraction; Phrasal evidence; Sentential evidence; Role fillers; Event extraction; Sentential event recognizer; Plausible roll-filler recognizer | 2009 |
