HAMNER: Headword Amplified Multi-span Distantly Supervised Method for Domain Specific Named Entity Recognition
Shifeng Liu, Yifang Sun, Bing Li +2
To tackle Named Entity Recognition (NER) tasks, supervised methods need to obtain sufficient cleanly annotated data, which is labor and time consuming. On the contrary, distantly s…
Antonym-Synonym Classification Based on New Sub-space Embeddings
Muhammad Asif Ali, Yifang Sun, Xiaoling Zhou +2
Distinguishing antonyms from synonyms is a key challenge for many NLP applications focused on the lexical-semantic relation extraction. Existing solutions relying on large-scale co…
Low ionospheric reactions on tropical depressions prior hurricanes
Aleksandra Nina, Milan Radovanović, Boško Milovanović +3
We study the reactions of the low ionosphere during tropical depressions (TDs) which have been detected before the hurricane appearances in the Atlantic Ocean. We explore 41 TD eve…
Behaviour of electron content in the ionospheric D-region during solar X-ray flares
M. Todorović Drakul, V. M. Čadež, J. Bajčetić +3
One of the most important parameters in ionospheric plasma research also having a wide practical application in wireless satellite telecommunications is the total electron content…
Ionospheric D-region temperature relaxation and its influences on radio signal propagation after solar X-flares occurrence
Jovan Bajčetić, Aleksandra Nina, Vladimir M. Čadež +1
In this paper our attention is focused on relations between radio signal propagation characteristics and temperature changes in D-region af- ter solar X-flare occurrence. We presen…
