Abstract

An apparatus and method provide logic for processing information. In one implementation, an apparatus includes a receiving unit configured to receive a selection of displayed content from a user. An obtaining unit is configured to obtain data corresponding to the selection. The data includes text data. An identification unit is configured to identify a keyword within the text data, and a storage unit is configured to generate a command to transmit the keyword to a device.

Claims

1. An information processing apparatus, comprising:

a display capable of displaying content;

a selecting unit configured to receive touch input from a first user, the touch input comprising a tracing indicative of a region of the display, and to determine a selection of the displayed content based at least in part on the touch input from the first user;

an obtaining unit configured to obtain data corresponding to the selection, the data comprising text data including a plurality of words;

an identification unit configured to identify an important keyword from the plurality of words; and

a control unit configured to;

generate a command to transmit the keyword to a device;

receive, from the first user, information identifying a second user, the second user being an intended recipient of the keyword;

generate a command to transmit the keyword and the received information to the device, the device being configured to transmit the keyword to the second user; and

determine whether to perform highlighting on the device based on the keyword and when the same display content is being displayed for both the first user and the second user at the same time.

2. The information processing apparatus of claim 1, wherein the displayed content comprises at least a first portion of an electronic document.

3. The information processing apparatus of claim 2, wherein the obtaining unit is further configured to receive information associated with the electronic document and information associated with the selection.

4. The information processing apparatus of claim 3, wherein:

the document information comprises a location of the displayed content within the electronic document; and

the selection information comprises at least one of (i) a type of user activation associated with the selection or (ii) a plurality of activation positions associated with the type of user activation.

5. The information processing apparatus of claim 4, wherein the obtaining unit is further configured to:

determine a second portion of the electronic document that includes the selection, based on at least the document information; and

obtain the text data corresponding to the selection from within the second portion, based on at least the selection information.

6. The information processing apparatus of claim 1, wherein a storage unit is further configured to store the text data in a document database.

7. The information processing apparatus of claim 1, wherein the identification unit is further configured to decompose the text data into a plurality of morphemes.

8. The information processing apparatus of claim 7, wherein the identification unit is further configured to:

receive morpheme data from a storage unit; and

decompose the text data into the plurality of morphemes, based on at least the morpheme data.

9. The information processing apparatus of claim 7, wherein the identification unit is further configured to:

determine grammatical roles corresponding to the morphemes; and

assign the morphemes to corresponding ones of a plurality of word classes, based on at least the determined grammatical roles.

10. The information processing apparatus of claim 9, wherein the identification unit is further configured to receive contextual information associated with the text data.

11. The information processing apparatus of claim 10, wherein the identification unit is further configured to identify a first subset of the morphemes based on at least the contextual information, the first morpheme subset being relevant to the text data.

12. The information processing apparatus of claim 11, wherein:

the identification unit is further configured to identify a second subset of the morphemes based on at least the contextual information, the second morpheme subset being irrelevant to the text data; and

the second morpheme subset comprises at least one of (i) a linguistic element that lacks a lexical definition or (ii) a morpheme having a meaning that is irrelevant to the obtained text data.

13. The information processing apparatus of claim 11, wherein the identification unit is further configured to:

select the keyword from the first morpheme subset;

determine, based on the contextual information, a keyword meaning associated with the keyword; and

compute a frequency at which the keyword occurs within the text data.

14. The information processing apparatus of claim 13, wherein the identification unit is further configured to assign a score to the keyword, based on at least the computed frequency.

15. The information processing apparatus of claim 14, wherein the storage unit is further configured to store, in the keyword database, at least one of the keyword meaning of the keyword, the score assigned to the keyword, a location of the keyword within the electronic document, or a portion of the obtained text data that includes the keyword.

16. The information processing apparatus of claim 2, wherein:

the control unit is further configured to generate a command to transmit at least one of information associated with the electronic document or information associated with the selection to the device.

17. The information processing apparatus of claim 1, further comprising a transmission unit configured to:

receive the command from the control unit; and

transmit the keyword to the device, in response to the received command.

18. A computer-implemented method for processing information, comprising:

displaying content on a display;

receiving touch input from a first user, the touch input comprising a tracing indicative of a region of the display;

determining a selection of the displayed content based at least in part on the touch input;

obtaining data corresponding to the selection, the data comprising text data including a plurality of words;

identifying, using a processor, an important keyword from the plurality of words;

generating a command to transmit the keyword to a device;

receiving, from the first user, information identifying a second user, the second user being an intended recipient of the keyword;

generating a command to transmit the keyword and the received information to the device, the device being configured to transmit the keyword to the second user; and

determining whether to perform highlighting on the device based on the keyword and when the same display content is being displayed for both the first user and the second user at the same time.

19. A non-transitory, computer-readable storage medium storing a program that, when executed by a processor, causes the processor to perform a method for processing information, comprising:

displaying content on a display;

receiving touch input from a first user, the touch input comprising a tracing indicative of a region of the display;

determining a selection of the displayed content based at least in part on the touch input;

obtaining data corresponding to the selection, the data comprising text data including a plurality of words;

identifying an important keyword from the plurality of words;

generating a command to transmit the keyword to a device;

receiving, from the first user, information identifying a second user, the second user being an intended recipient of the keyword;

generating a command to transmit the keyword and the received information to the device, the device being configured to transmit the keyword to the second user; and

determining whether to perform highlighting on the device based on the keyword and when the same display content is being displayed for both the first user and the second user at the same time.
