Weather Forecast Creator
The signed weather forecast web page was based on the regular weather forecasts produced by the Royal Dutch Meteorological Institute (KNMI). While maintaining the content, the original free-form sentences of these weather forecasts were standardised, to make the input suitable for (semi) automatic conversion to sign language. For this, a model consisting of 20 sentence patterns was used, and all possible words and phrases that could fill each slot in the pattern were added. An example of a sentence pattern is “The weather forecast of the KNMI, drawn up on [WEEKDAY][NUMBER][MONTH], and valid till midnight.” This pattern has three slots, for the day of the week, for the month and for the day of the month respectively. In a pattern, the slots are indicated with the category of the word that is to be filled in. Many patterns consist entirely of slots, for example “[TIME] [WEATHER CONDITION]”. The category TIME consists of phrases such as “in the morning”, “in
the afternoon”, “during the whole day”, “now and then”, etc., and the category WEATHER CONDITION of phrases as “rain”, “snow”, “sunny”, “fog”, “clouded”, “heavily clouded”, “veil clouds” etc. The model was based on 100 real life weather forecasts from the Netherlands, representing most types of Dutch weather.
