« In the old days, if you would do a search in a search engine, you would get a lot of irrelevant hits that for some reason contained the keyword you used. Nowadays search engines give you much better results, because they put the keyword into context. This new way of…

« Content mining, machine learning, text and data mining (TDM) and data analytics all refer to the process of obtaining information through machine-read material. Faster than a human possibly could, machine-learning approaches can analyze data, metadata and text content; find structural similarities between research problems in unrelated fields; and synthesize content…

« One of the things you can do with textmining, is discovering conceptually related items within a collection of text and data. Want to know more? Anas Alzogbi is research assistant and doctoral student at the University of Freiburg.  He explains Recommenders and Filtering in four short movies. « 

« It’s time for the second part of ‘Key concepts and areas in TDM explained’. This time, Jevin West tells us more about  “Text and Data Mining” and “Knowledge Representation” in three short videos. (…) »

« VOSviewer is a software tool for constructing and visualizing bibliometric networks. These networks may for instance include journals, researchers, or individual publications, and they can be constructed based on citation, bibliographic coupling, co-citation, or co-authorship relations. VOSviewer also offers text mining functionality that can be used to construct and visualize…

« Nous avons déjà vu sur ce blog deux approches : comment faire vos premiers pas avec une méthode basique d’analyse fréquentiste, en comparant {tidytext} et {tm} dans notre premier billet. Nous avons poursuivi avec les n-grammes dans notre second numéro. Suite des hostilités aujourd’hui…

« Frédéric Hélein, membre de la Bibliothèques Scientifique Numérique 7 et directeur scientifique du RNBM, analyse l’enjeu pour les chercheurs de la directive européenne sur le droit d’auteur en cours de révision à Bruxelles. Le futur texte aura des conséquences profondes sur la diffusion de la recherche et sur des nouvelles…

« What are the benefits of text and data mining (TDM) and how can its practices be applied in science? We asked recognised experts in the field to introduce key areas and concepts in short videos. The videos will be released during the following weeks in a series of blogposts. Today…

« Text and data mining (TDM), the automated analysis of digital data searching for trends, correlations and patterns, is rapidly gaining prominence due to exponentially increasing amounts of digital data (‘Big Data’) and decreasing technology prices. TDM enables researchers to access and analyse material that was previously impossible to process. Is…

« From September 6th– September 8th, over 200 people with an interest in open science came together in Athens for the Open Science Fair. OpenMinTeD was one of the co-organisers, and also organised a workshop on text and data mining. The first part of the workshop showcased successful…
