Molina M, Sanchez-Soriano J, Corcho O - Sensors (Basel) (2015)

Bottom Line: In this paper, we discuss the feasibility of using geographic knowledge from public databases available on the Web (such as OpenStreetMap, Geonames, or DBpedia) to automatically construct such descriptions.We present a general method that uses such information to generate sensor descriptions in natural language.The results of the evaluation of our method in a hydrologic national sensor network showed that this approach is feasible and capable of generating adequate sensor descriptions with a lower development effort compared to other approaches.

ABSTRACT
Providing descriptions of isolated sensors and sensor networks in natural language, understandable by the general public, is useful to help users find relevant sensors and analyze sensor data. In this paper, we discuss the feasibility of using geographic knowledge from public databases available on the Web (such as OpenStreetMap, Geonames, or DBpedia) to automatically construct such descriptions. We present a general method that uses such information to generate sensor descriptions in natural language. The results of the evaluation of our method in a hydrologic national sensor network showed that this approach is feasible and capable of generating adequate sensor descriptions with a lower development effort compared to other approaches. In the paper we also analyze certain problems that we found in public databases (e.g., heterogeneity, non-standard use of labels, or rigid search methods) and their impact in the generation of sensor descriptions.

sensors-15-16009-f004: Main components of the method.

Mentions: This section describes the method that we designed to generate textual descriptions for sensors using open geographic data (Figure 4). The method takes the geographical coordinates (latitude and longitude) of each sensor location and the sensor type, i.e., the type of physical quantity measured by each sensor (e.g., water level, rainfall, flow, etc.), as input. The method also takes input data from the selected geographic databases (OpenStreetMap, Geonames, DBpedia, and Panoramio). As output, the method generates text descriptions that identify the geographical locations of sensors in natural language, for example: “the Ebro River at Ascó” or “the Ribarroja reservoir”. To construct the descriptions, our method performs two main processes: (1) template-based text generation and (2) geographic features extraction. The next sections describe these two processes in more detail.
