Granthika’s search engine supports the following semantic elements:
literal
: Text enclosed in double quotation marks, such as “pipe,” “Sherlock Holmes,” “he was excited.”
type
: The types
defined in Granthika’s are: , , , and .
individual
: An instance of a type
is an individual
. Sherlock Holmes is an individual
of the type
character.
data-property
: A relationship between a type
and a literal
. The query characters containing “Sherlock”
uses the data-property
contains
to find all characters which have the string “Sherlock” in their names, and similarly scenes containing “Sherlock”
finds all scenes with the string “Sherlock” within their text.
object-property
: A relationship between a type
and an individual
or two individuals
. The currently defined object-properties
are is-participant
, is-sub-event
, have-location
, and depicts
. These allow queries such as events with participant Sherlock Holmes
.
All discourse elements are represented by the term Discourse
. Manuscript
is the top-level discourse element.
The following semantic patterns are recognized by Granthika’s search engine:
literal
only: Queries such as “agonized letters”
and “no fear”
. The search engine looks for the single word entered, or (if entered) a phrase, and–in the latter case–if there are no results, falls back to searching for individual words within the search term. The results will list discourse elements that contain the matches found and highlights the occurrences of the entered search term.
type
only: Will find all the individuals
of the given type. So event
or events
will find all events like “Watson Writes Memoirs.”
individual
only: Will find individuals
that have the entered name. So Holmes
will find “Sherlock Holmes” (a character) and “Holmes in Practise” (an event), and office
will find “Sherlock’s Office” (a location).
type object-property individual
: Will find all individuals
from the given type
which have the relationship specified by the given object-property
with the individual
. So events with participant Sherlock Holmes
will find all events that have Sherlock Holmes as a participant, and characters mentioned Chapter 2
will find all characters that are mentioned in Chapter 2.
object-property invidual
: Works like type object-property individual
, but will infer the type
of the individual
. So have location office
infers that you are looking for events, and will find all events that have Sherlock’s Office as a location. Similarly, mentions Holmes
infers that you are looking for all discourse elements that mention Sherlock Holmes. mentioned by Chapter 1
will infer that you are looking for any story element mentioned within Chapter 1.
type data-property literal
: Will find individuals
from the given type
that have the relationship specified by the data-property
with the given literal
. So characters containing “Ronder”
will find all characters that have the string “Ronder” in their name (Mr. Ronder and Mrs. Ronder).
object-property
alone: Finds all individuals
that engage in a relationship via the given object-property
. So participants
will find all characters who participate in any events, and depicting
will find all discourse elements that depict any events.
data-property literal
: This works like type data-property literal
, but looks for any individual
, disregarding its type
. So contain “pipe”
will find any discourse element that contains “pipe” within its text.
individual object-property
: Finds all individuals
which are objects
for the given object-property
. So Holmes in Practise participant
will find all the characters who participate in the event “Holmes in Practise,” and “Allahabad locate” will find all the events that have Allahabad as a location.
