【摘要】:人們在戶外行走時,通常使用自然語言表達其對自身位置的感知,在計算機中如何將定性的自然語言位置描述轉換為定量的圖形語言是地理信息系統(tǒng)、人工智能等領域面臨的挑戰(zhàn)。該文提出一種基于行人位置描述的道路模擬表達方法,將自然語言位置描述轉換為道路模擬地圖。首先設計一組空間認知實驗,探討道路上的行人在戶外如何使用自然語言描述當前位置;然后基于行人的每條自然語言位置描述估算該位置的候選區(qū)域,在候選區(qū)域中隨機產(chǎn)生該位置的一對坐標值;最后將行人在路上經(jīng)過的多個位置點坐標數(shù)據(jù)組合,采用直線擬合和概率擬合兩種方法對該道路進行模擬表達。實驗結果表明,該文方法能達到較好的模擬表達效果,為自然語言到圖形語言的轉換研究奠定了基礎。
[Abstract]:When people walk outdoors, they usually use natural language to express their perception of their own position. How to convert qualitative description of natural language position into quantitative graphic language in computer is geographic information system (GIS). Challenges in areas such as artificial intelligence. In this paper, a road simulation representation method based on pedestrian location description is proposed, which converts natural language location description into road simulation map. First, a set of spatial cognitive experiments was designed to explore how pedestrians on the road use natural language to describe the current location outdoors, and then to describe the candidate area for estimating the location based on each natural language location of the pedestrian. A pair of coordinate values of the position are randomly generated in the candidate region. Finally, the coordinate data of multiple points of pedestrian passing on the road are combined, and the road is simulated by two methods: straight line fitting and probabilistic fitting. The experimental results show that this method can achieve a good performance of simulation and expression, which lays a foundation for the study of the transformation from natural language to graphic language.
