Knowledge formalization is one of the main tasks in research of systems complexity. It is usually based on the development and analysis of different kind of models. Structural modeling (SM) is proposed as a succesfull approach which manages this task. The main idea of SM is building and analysis of mutually transformable models. Therefore an appropriate software for development and analysis of models has been launched by RTU FCSIT .

With semantic parsing technologies developed within Project Nr.2 of the National Research Programme SOPHIS we have achieved sufficient international recognition to be able to participate in a high-quality consortium in the area of BigData. Together with BBC, Deutche Welle, Univerity of Edinburgh, University Colledge of London, IDIAP from Switzerland, and Priberam from Portugal we have prepared an H2020 ICT-16 proposal on BigData media-monitoring.

UL IMCS participated in International Workshop on Semantic Evaluation (SemEval-2015) and specifically in Task 18 on Broad-Coverage Semantic Dependency Parsing (SDP 2015). Broad-coverage semantic dependency parsing is the task of recovering sentence-internal predicate–argument relationships for all content words, i.e. the semantic structure constituting the relational core of sentence meaning. SDP 2015 competition provided training data and evaluated SDP parsers for English, Czech, and Chinese languages.

The FrameNet based semantic parsing technology for Latvian developed within the National Research Programme is already exploited industrially through partnership projects with Latvian News Agency (LETA) and is described in several scientific papers ublished in international conferences. Meanwhile none of this provided an independent verification for the quality of our semantic parsing technology compared to the best parsing systems in the world. To clarify this and to rise the international recognition for UL IMCS achievements, we took part in the above-mentioned SemEval-2015, Task 18 international competition, where research teams from whole world compete to achieve the best parsing results for shared semantic parsing tasks.

Results of Sem Eval 2015

We (Riga-team) are proud to finish this competition among the three best teams with results largely on par with Peking and Lisbon research teams. In this and last year SDP competitions took part more than 10 reasearch teams, including Cornegie Mellon University (CMU) from US, which was considered the leader in FrameNet semantic parsing. Results are available at http://svn.emmtee.net/sdp/public/2015/scores.ods . It is interesting to note that although we (Riga-team) were third on the official LF metric „F1-score for labeled graphs”, in other parameters we were first. For example, for the proportion of completely correctly parsed sentences in Chinese (LM metric: labeled exact match) we were first with slightly better result than Peking team.

A paper describing our system has been accepted for publication in NAACL’2015 conference

Activities

The project is building tools for wireless sensor development, including the testbed with sensor modules, that can be tested and profiled while deployed at the Institute of Electronics and Computer Science. The current activities include remote programming and remote boot support, configuration and service server development. There is also work being done for the mobile testbed that will be used for ITS research and systems validation.

The second aspect of the project involves applications of cyber physical systems for health care. THe researchers are developing a wearable and wireless heart monitor, currently in the prototype desin phase. Another prototype being developed and tested is the body dynamics sensor system containing several accelerometer and gyroscope modules that in concert can deliver a shape of body such as back or a knee joint in real time and assist in rehabilitation. Currently the back shape prototype is built and the new version is under development, including additional sensors for better precision.

The third area is intelligent transportation systems. The research group is in the process of developing a smart sensor interface for vehicle position and orientation in the environment, using such sensors as LiDAR Velodyne HDL-32E, RTK-GPS OXTS RT3003 and OXTS RT-Base-2. These devices are being adapted and tested for eventual participation in the Grand Cooperative Driving Challenge 2016. In addition, work is being done in the field of image processing and analysis, including object identification on a noisy backround for road analyisis in real time, as well as driver face image analysis for the signs of fatigue.
