[0076] Table 2 shows an answer feature set corresponding to the
"Technology Trigger" stage in the technology lifecycle.
[0077] A common feature value, a unit of the feature value and a
weighting factor are set in the answer feature set. The weighting
factor is used to obtain a similarity, which is an index for
determining a stage where a feature set of a specific technology
belongs to.
[0078] In some of the technologies, feature values of a specific
stage may be overlapped with feature values of the other stages.
Therefore, the answer feature set creation module 140 obtains
common feature values for discriminating feature values of each
stage and creates an answer feature set of each stage, in a method
of excluding such cases as collisions occur among the stages by
removing feature values overlapped among different stages and
removing extreme feature values in each stage.
[0079] If a specific technology is inputted through the interface
module 120, the stage determination module 150 acquires feature
values and creates a feature set for predefined features by
searching the bibliographic database 110 for the specific
technology, and determines a stage where the specific technology
belongs to in the technology lifecycle by comparing the created
feature set with the answer feature set.
[0080] Referring to FIG. 4 for the stage determination module 150,
the stage determination module 150 includes a feature-related
information acquisition unit 152, a feature value calculation unit
154, a feature set creation unit 156, a feature set comparison unit
158 and a stage determination unit 160.
[0081] If a specific technology is inputted, the feature-related
information acquisition unit 152 acquires feature-related
information for calculating feature values of features contained in
a predefined feature set by searching the bibliographic database
110.
[0082] The feature value calculation unit 154 obtains a feature
value for each feature using the acquired feature-related
information.
[0083] The feature set creation unit 156 creates a feature set of
the specific technology containing the feature values calculated by
the feature value calculation unit 154.
[0084] The feature set comparison unit 158 compares the feature set
of the specific technology with the answer feature set of each
stage. At this point, the feature set comparison unit 158 obtains a
similarity to the answer feature set of each stage by applying a
weighting factor to each feature value contained in the feature set
of the specific technology.
[0085] In addition, if there exists an absolute criterion, the
feature set comparison unit 158 compares a feature value
corresponding to the absolute criterion among the feature set of
the specific technology with a corresponding feature value of the
answer feature set. Here, the absolute criterion may be a criterion
randomly selected from the feature set.
[0086] In addition, according to a feature selection flow set in a
previously constructed decision tree, the feature set comparison
unit 158 may compare a corresponding feature value contained in the
feature set of the specific technology with a feature value
according to the feature selection flow set in the decision tree.
The decision tree may be formed as shown in FIG. 9. That is, the
feature value according to the feature selection flow set in the
decision tree is a feature value of the answer feature set.
[0087] Constitutional components of the decision tree are
configured using features, and the form and method of the decision
tree correspond to those of a general decision tree, and thus
detailed descriptions thereof will be omitted.
[0088] As a result of comparison of the feature set comparison unit
158, the stage determination unit 160 determines a stage of an
answer feature set having a common feature value closest to a
feature value of the specific technology feature set among the
common feature values of the answer feature set of each stage as a
stage where the specific technology belongs to in the technology
lifecycle.
[0089] For example, if the feature set of the specific technology
is closest to the third stage of the answer feature set as a result
of comparison between the feature set of the specific technology
and the answer feature set, the stage determination unit 160
determines that the specific technology belongs to the third stage
in the technology lifecycle.
[0090] In addition, the stage determination unit 160 may determine
a stage having a feature value finally selected according to the
feature selection flow of the decision tree as a stage where the
specific technology belongs to in the technology lifecycle.
[0091] The visualization module 170 visualizes the technology
lifecycle which shows the stage where the specific technology
belongs to. That is, the visualization module 170 expresses the
specific technology on the technology lifecycle and outputs the
technology lifecycle.
[0092] FIG. 5 is a flowchart illustrating a computer-implemented
method of determining a stage of a technology using a technology
lifecycle by a stage determination apparatus according to the
present invention.
[0093] Referring to FIG. 5, the stage determination apparatus
creates a feature set for each technology positioned on a
technology lifecycle S502.
[0094] A technique of the stage determination apparatus for
creating a feature set for each technology will be described in
detail with reference to FIG. 6.
[0095] After performing step S502, the stage determination
apparatus obtains a common feature value of feature sets of
technologies belonging to the same stage in the technology
lifecycle and creates an answer feature set of each stage S504.
That is, the stage determination apparatus obtains common feature
values for discriminating feature values of the technologies
belonging to the same stage in the technology lifecycle from
feature values of the other stages, and creates an answer feature
set of each stage based on the common feature values.
[0096] If a specific technology is inputted S506 after performing
step S504, the stage determination apparatus determines a stage
where the specific technology belongs to in the technology
lifecycle S508. A computer-implemented method of determining a
stage where the specific technology belongs to in the technology
lifecycle will be described in detail with reference to FIG. 7.
[0097] After performing step S508, the stage determination
apparatus visualizes the'technology lifecycle which shows the stage
where the specific technology belongs to S510.
[0098] That is, the stage determination apparatus displays the
technology lifecycle which shows the stage where the specific
technology belongs to as shown in FIG. 8.
[0099] Referring to FIG. 8, the specific technology, as well as the
other technologies, is displayed in each of the predefined stages
of the technology lifecycle which shows the stage where the
specific technology belongs to.
[0100] That is, the technology lifecycle described above includes
five stages in total, such as a Technology Trigger stage, a Peak of
Inflated Expectations stage, a Trough of Disillusionment stage, a
Slope of Enlightenment stage, and a Plateau of Productivity
stage.
[0101] Each stage shows technologies belonging to the stage, as
well as the specific technology. For example, technologies of
Biometric Authentication Methods, Internet Micropayment System,
Interactive TV, Predictive Analytic, Electronic Paper, Location
Aware Application, and Speech Recognition are shown in the Slope of
Enlightenment stage, and specific technology `A` is shown in the
Peak of Inflated Expectations stage.
[0102] The user may easily confirm a stage where the specific
technology inputted by the user belongs to using the visualized
technology lifecycle.
[0103] Here, although the stages of the technology lifecycle are
expressed as five stages in total, such as the Technology Trigger
stage, the Peak of Inflated Expectations stage, the Trough of
Disillusionment stage, the Slope of Enlightenment stage and the
Plateau of Productivity stage, the stages of the technology
lifecycle can be set or modified in a different form such as a
first stage, a second stage, a third stage and the like.
[0104] FIG. 6 is a flowchart illustrating a method of creating a
feature set for each technology by a stage determination apparatus
according to the present invention.
[0105] Referring to FIG. 6, the stage determination apparatus
acquires feature-related information for calculating feature values
of features contained in a predefined feature set by searching the
bibliographic database for the technologies S602.
[0106] Then, the stage determination apparatus obtains a feature
value of each feature by the technology using the acquired
feature-related information S604 and creates a feature set
containing the calculated feature values for each technology
S606.
[0107] FIG. 7 is a flowchart illustrating a computer-implemented
method of determining a stage of a specific technology by a stage
determination apparatus according to the present invention.
[0108] Referring to FIG. 7, if a specific technology is inputted
S702, the stage determination apparatus acquires feature-related
information for calculating feature values of features contained in
a predefined feature set by searching the bibliographic database
S704.
[0109] After performing step S704, the stage determination
apparatus obtains a feature value for each feature using the
acquired feature-related information S706 and creates a feature set
of the specific technology constructed using the calculated feature
values S708.
[0110] After performing step S708, the stage determination
apparatus compares the feature set of the specific technology with
the answer feature set of each stage S710 and determines a stage of
an answer feature set having the highest similarity as a result of
comparison as a stage where the specific technology belongs to in
the technology lifecycle S712.
[0111] Although it is described above that a similarity is
calculated by comparing the feature set of the specific technology
with the answer feature set of each stage and a stage is determined
using the calculated similarity, the stage determination apparatus
may determine a stage of the specific technology using an absolute
criterion or a decision tree.
[0112] That is, if there exists an absolute criterion, the stage
determination apparatus may compare a feature value according to
the absolute criterion among the feature set of the specific
technology with a corresponding feature value of the answer feature
set, and determine a stage having a feature value of the highest
similarity as a result of comparison as a stage where the specific
technology belongs to in the technology lifecycle.
[0113] In addition, according to a feature selection flow set in a
previously constructed decision tree, the stage determination
apparatus may compare a corresponding feature value contained in
the feature set of the specific technology with a feature value
according to the feature selection flow set in the decision tree,
and determine a stage having a feature value finally selected
according to the feature selection flow of the decision tree as a
stage where the specific technology belongs to in the technology
lifecycle.
[0114] While the present invention has been described with
reference to the particular illustrative embodiments, it is not to
be restricted by the embodiments but only by the appended claims.
It is to be appreciated that those skilled in the art can change or
modify the embodiments without departing from the scope and spirit
of the present invention.
