Unsupervised Open Relation Extraction

We explore methods to extract relations between named entities from free text in an unsupervised setting. In addition to standard feature extraction, we develop a novel method to re-weight word embeddings. We alleviate the problem of features sparsity using an individual feature reduction. Our approach exhibits a significant improvement by 5.8% over the state-of-the-art relation clustering scor...

Extraction of Keywords of Novelties From Patent Claims

There are growing needs for patent analysis using Natural Language Processing (NLP)-based approaches. Although NLP-based approaches can extract various information from patents, there are very few approaches proposed to extract those parts what inventors regard as novel or having an inventive step compared to all existing works ever. To extract such parts is difficult even for human annotators ...

Automatic Extraction of Semantic Relations from Patent Claims

In this paper, we propose a set of techniques to extract the semantic relations from patent claims and extend it to facilitate the comparisons among patent claims on the basis of the semantic structures. The system could parse and annotate every claim sentence and extract the desired semantic information from the patent claim texts using the regular expression pattern matching techniques. The e...

Open Relation Extraction and Grounding

Previous open Relation Extraction (open RE) approaches mainly rely on linguistic patterns and constraints to extract important relational triples from large-scale corpora. However, they lack of abilities to cover diverse relation expressions or measure the relative importance of candidate triples within a sentence. It is also challenging to name the relation type of a relational triple merely b...

Metastasizing patent claims on BRCA1.

Many patents make claims on DNA sequences; some include claims on oligonucleotides related to the primary patented gene. We used bioinformatics to quantify the reach of one such claim from patent 4,747,282 on BRCA1. We find that human chromosome 1 (which does not contain BRCA1) contains over 300,000 oligonucleotides covered by this claim, and that 80% of cDNA and mRNA sequences contributed to G...
