1. 1. From Numerical Sensor Data to Semantic Representations : A Data-driven Approach for Generating Linguistic Descriptions

   Författare :Hadi Banaee; Amy Loutfi; Erik Schaffernicht; Andrey Kiselev; Mobyen Ahmed; Antonio Chella; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Semantic representations; Conceptual spaces; Natural language generation; Temporal rule mining; Physiological sensors; Health monitoring system;

   Sammanfattning : In our daily lives, sensors recordings are becoming more and more ubiquitous. With the increased availability of data comes the increased need of systems that can represent the data in human interpretable concepts. LÄS MER

3. 2. Splitting rocks: Learning word sense representations from corpora and lexica

   Författare :Luis Nieto Piña; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; language technology; natural language processing; distributional models; semantic representations; distributed representations; word senses; embeddings; word sense disambiguation; linguistic resources; corpus; lexicon; machine learning; neural networks;

   Sammanfattning : The representation of written language semantics is a central problem of language technology and a crucial component of many natural language processing applications, from part-of-speech tagging to text summarization. These representations of linguistic units, such as words or sentences, allow computer applications that work with language to process and manipulate the meaning of text. LÄS MER

4. 3. Semantic Mapping in Warehouses

   Författare :Saeed Gholami Shahbandi; Björn Åstrand; Roland Philippsen; Antanas Verikas; Martin Magnusson; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automation; Robotics; Mapping; Semantic Maps; Warehouse Automation;

   Sammanfattning : This thesis and appended papers present the process of tacking the problem of environment modeling for autonomous agent. More specifically, the focus of the work has been semantic mapping of warehouses. A semantic map for such purpose is expected to be layout-like and support semantics of both open spaces and infrastructure of the environment. LÄS MER

5. 4. Towards semantic language processing

   Författare :Anna Jonsson; Johanna Björklund; Marco Kuhlmann; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Weighted tree automata; abstract meaning representation; contextual hyperedge replacement grammar; hyperedge replacement grammar; semantic modelling; the N best problem; Computer Science; datalogi; datorlingvistik; computational linguistics;

   Sammanfattning : The overall goal of the field of natural language processing is to facilitate the communication between humans and computers, and to help humans with natural language problems such as translation. In this thesis, we focus on semantic language processing. LÄS MER

7. 5. Ensembles of Semantic Spaces : On Combining Models of Distributional Semantics with Applications in Healthcare

   Författare :Aron Henriksson; Hercules Dalianis; Martin Duneld; Nigel Collier; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; natural language processing; machine learning; distributional semantics; ensemble learning; semantic space ensembles; medical informatics; electronic health records; Computer and Systems Sciences; data- och systemvetenskap;

   Sammanfattning : Distributional semantics allows models of linguistic meaning to be derived from observations of language use in large amounts of text. By modeling the meaning of words in semantic (vector) space on the basis of co-occurrence information, distributional semantics permits a quantitative interpretation of (relative) word meaning in an unsupervised setting, i.
