KB features for already disambiguated mentions to improve CCR.  ...  Experimental results on two different corpora, news-centric and web-centric, demonstrate significant gains over state-of-the-art baselines for both CCR and NEL.  ...  For NEL ground-truth construction, we link the entities to their Wikipedia pages (using Freebase's "on the web" property).  ...

Discovering Entities with Just a Little Help from You

Jaspreet Singh, Johannes Hoffart, Avishek Anand
2016 Proceedings of the 25th ACM International on Conference on Information and Knowledge Management - CIKM '16  
For popular entities, such a representation can be easily mined from Wikipedia, and many current entity disambiguation and linking methods make use of this fact.  ...  We propose novel human-in-the-loop retrieval methods for generating candidates based on gradient interleaving of diversification and textual relevance approaches.  ...  Effect of Rank 1 Owing to the 3 distinct classes of retrieval models, we find that each class selects a different document at rank 1.  ...

Little Knowledge Rules the Web: Domain-Centric Result Page Extraction [chapter]

Tim Furche, Georg Gottlob, Giovanni Grasso, Giorgio Orsi, Christian Schallhart, Cheng Wang
2011 Lecture Notes in Computer Science  
It models domain knowledge about (1) records and attributes of the domain, (2) low-level (textual) representations of these concepts, and (3) constraints linking representations to records and attributes  ...  These approaches trade intensive user interaction for precision.  ...  Figure 3 shows the identified clusters for the Zoopla case: one rooted at D 2 for featured properties, one at D 3 for standard properties.  ...

Namesake alias mining on the Web and its role towards suspect tracking

Tarique Anwar, Muhammad Abulaish
2014 Information Sciences  
The retrieved webpages are modeled into a graph, and a clustering algorithm is applied to disambiguate the webpages.  ...  Additionally the contribution includes the disambiguation technique that doesn't need to have a pre-determined number of clusters to be generated and the light-weight text pattern based alias mining technique  ...  The authors would also like to thank King Abdulaziz City for Science and Technology (KACST) and King Saud University for their support.  ...

Event abstraction in process mining: literature review and taxonomy

Sebastiaan J. van Zelst, Felix Mannhardt, Massimiliano de Leoni, Agnes Koschmider
2020 Granular Computing  
Most process mining techniques assume that the event data are of the same and/or appropriate level of granularity.  ...  Analyzing event data, i.e., the focus of process mining, yields a detailed understanding of the process, e.g., we are able to discover the control flow of the process and detect compliance and performance  ...  as you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons licence, and indicate if changes were made.  ...

NLP-based Ontology Learning from Legal Texts. A Case Study

Alessandro Lenci, Simonetta Montemagni, Vito Pirrelli, Giulia Venturi
2007 International Conference on Artificial Intelligence and Law  
We use a fully-implemented ontology learning system (T2K) that includes a battery of tools for Natural Language Processing (NLP), statistical text analysis and machine language learning.  ...  Evaluated results, however preliminary, are very encouraging, showing the great potential of NLP-powered incremental systems like T2K for accurate large-scale semi-automatic extraction of legal ontologies  ...  In fact, of all verb-term pairs attested in the corpus only a subset of highly salient such pairs is considered for clustering by CLASS.  ...

2003 Conference and Labs of the Evaluation Forum  
For its first birthday, the LIC2M has participated to the Small Multilingual Track of CLEF 2003.  ...  Our system is based on a deep linguistic analysis of documents and queries and on an original search algorithm inherited from the Spirit (EMIR) system.  ...  The positional properties of this large set of categories (137 for French, 120 for English, 100 for Spanish and currently only 38 for German) will allow a very effective disambiguation, as we will see  ...

A scaffolding approach to coreference resolution integrating statistical and rule-based models

2017 Natural Language Engineering  
Our approach combines many advantages: it incrementally builds clusters integrating joint information about entities, uses rules for deterministic phenomena, and integrates rich lexical, syntactic, and  ...  We describe a scaffolding approach to the task of coreference resolution that incrementally combines statistical classifiers, each designed for a particular mention type, with rule-based models (for sub-tasks  ...  From this data, for each mention, we extract at most one positive (coreferent) and possibly multiple negative (non-coreferent) training data points consisting of the pair of the corresponding mention and  ...
