Abstract:
1. An information processing apparatus comprising: a memory device for storing a list of evaluation expressions including a list of first phrases which are classified as belonging to a first kind as expressions of evaluation of commercial products and a list of second phrases which are classified as belonging to a second kind that differs from said first kind, and a controller acquiring texts including each of a plurality of commercial product names to be analyzed, with respect to the respective commercial product names, from a storage device when said plurality of commercial product names are entered into said controller, extracting said first phrases and said second phrases respectively from the acquired texts with respect to said commercial product names, and generating a graph representing evaluation points as values corresponding to the differences between counts of said first phrases and said second phrases, wherein said controller extracts evaluation information representing modification relations between nouns as a type of attribute expressions and verbs or adjectives as a type of evaluation expressions, from the acquired texts about said commercial product names from said storage device, extracts reputation information including said first phrases and said second phrases in modified parts of the extracted evaluation information, and calculates the difference between the number of pieces of the reputation information including said first phrases and the number of pieces of the reputation information including said second phrases with respect to each of said attribute expressions, thereby determining said evaluation points, and then generates, as said graph, a bubble chart having coordinate axes representing said commercial product names and circles having sizes corresponding to the numbers of pieces of the reputation information, said circles being located at coordinates calculated from said evaluation points for the commercial product names with respect to each of said attribute expressions, wherein it assumed that W score P (Wi, index j) which is based on a distance Xij from index j (j is greater than or equal to 1, is less than or equal to n) and on a size for said circle of attribute expression Wi (i is greater than or equal to 1, is less than or equal to m) is determined by the equation, P (Wi, index j)=1/Xij+wi/10, when said controller generates said bubble chart, said controller calculates each P (Wi, index j) when j changes 1 through n in each i which changes 1 through m by using the equation, selects attribute expressions Wi of a predetermined higher number regarding said score based on scores P (Wi, index j) calculated about index 1 through index n, and plots said circles which correspond to selected attribute expressions Wi on said bubble chart.
