The natural language question is an easy way to phrase a search query,
where the APICP flag
keepnoise has been left off. Type in a
question which contains the elements you are looking for in the text.
There are really only these few rules to keep in mind.
An example of a "good" question to ask would be:
Have there been any corporate takeovers?
An example of a less desirable question would be:
What information is there on corporate takeovers?
The reason is that in this second question, the concept "
must be stated in the text along with the concept "
takeover" to be considered a match, probably excluding relevant responses;
any hit from a news article is implicitly understood to be information without
so stating. All you really need are the two important concepts "
Another "good" question might be:
Were there any corporate takeovers in Germany?
Have there been any power struggles in the Near East?
Where idiomatic expressions or phrases exist as entries in the Equivalence File, they will be meaningfully processed as a whole, whether so marked or not. The question parser will check for phrase entries in an entered query. If the word grouping is not known to be a phrase, the words will be processed separately, according to their individual associations. If it is important to you that the words of such an expression or phrase be processed as one unit and Metamorph does not recognize it as such, mark it as a phrase by putting it in quotes.
Once your question is entered, the question parser will select the
important words and denote them as root words, to be expanded into
sets from the known associations in the Equivalence File. These words
and all their equivalences are in the main passed to
PPM to be
searched for simultaneously while determining where answers to your
question might lie.
As a rule, unless escaped with a backslash (
\), hyphens are
stripped from the words on the query line before expanded to include
their associations in the Equivalence File and sent to the search
engine. Once passed to
SPM occurrences of those
words as separated by either hyphens or white space will be located.
