Toponym Resolution Based on Surface Difference among Candidates
地名等の固有名詞は自然言語処理における未知語処理問題の要因の一つであり,これを自動的に認識する手法が盛んに研究されている.本稿では,地名の所属国を自動的に推定することで,未知語としてノイズの原因となる可能性のある地名語句に情報を与えることを目的とする.固有名詞である地名の認識では地名辞書が用いられることが多いが,辞書ベースの手法では,辞書未登録語の問題が避けられない.不特定多数の外国の地名も含めた所属国の推定の実現のため,本稿では,地名辞書や文脈情報を全く使用せず,地名の表層情報のみを利用して,地名の所属国を自動的に判別する手法を提案する.地名については,言語的な類似性や地理的要因によって所属国の判別が困難な場合がある.本稿ではこの点に着目し,所属可能性の低い国の除去による候補の絞込み処理と ...

DM_NLP at SemEval-2018 Task 12: A Pipeline System for Toponym Resolution [PDF]
This paper describes DM-NLP’s system for toponym resolution task at Semeval 2019. Our system was developed for toponym detection, disambiguation and end-to-end resolution which is a pipeline of the former two. For toponym detection, we utilized the state-of-the-art sequence labeling model, namely, BiLSTM-CRF model as backbone.

Toponym Resolution on Historical Serial Sources
Various challenges are present in the resolution of toponyms from historical serial sources, where problems range from spelling errors to incorrect information. In this thesis, such problems are identified, design decisions for a resolution system are made, applicable heuristics from all over literature are gathered and complemented, the implementation

Institute for Communicating and Collaborative Systems Background. In the area of Geographic Information Systems (GIS), a shared discipline between informatics and geography, the term geo-parsing is used to describe the process of identifying names in text, which in computational linguistics is known as named entity recognition and classification (NERC).

Using Contexts and Constraints for Improved Geotagging of Human Trafficking Webpages
Extracting geographical tags from webpages is a well-motivated application in many domains. In illicit domains with unusual language models, like human trafficking, extracting geotags with both high precision and recall is a challenging problem.
