We also discuss LSOE results providing an error analysis. We have performed two evaluation rounds, each one using a different input corpus. The input of the first round was a corpus of 2.

In semantics, reference is generally construed as the relationships between nouns or pronouns and objects that are named by them. Hence, the word John refers to the. Wikipedia articles from Wikicorpus 4. We expect that LSOE obtains precision compatible with rule based Open IE systems and that it extracts relations that are not learned by them. We also calculate yield as proposed in 2. Evaluation setup. The evaluation of the system was carried by a manual assessment of the results. We compared LSOE with the two other rule based open extractors Re. Verb and Dep. OE systems. The type of parsing and the tools used in this task by each extractor is presented in Table 5. Table 5. The evaluated systems input. After running each system over the same input sentences, two human judges evaluated the triples generated by the systems as correct or incorrect, following the same procedure from 7. Uninformative or incoherent triples were classified as incorrect.

Only results from the subset of the data where the judges agree were considered for results evaluation. For instance, given the sentence Kantianism is the philosophy of Immanuel Kant, LSOE generated the triple Kantianism,is the philosophy of, Immanuel Kant and Dep. OE the triple Kantianism, is, the philosophy of Immanuel Kant, both labeled as correct. In contrast, Re. Verb generated the triple Kantianism, is, the philosophy, labeled as incorrect due to being uninformative. First round In the first evaluation round, over the Philosophy of Language domain, the judges reached agreement on 6. Table 4 gives an overview of the results of this evaluation round. It shows the number of triples extracted by each system and their classification as correct or incorrect. From the 3. 11 tuples extracted by the LSOE in the Philosophy of Language, 1.

LSOE with the best result around 0. Regarding the relation phrases inside the tuples, LSOE learned 1. Table 6. As expected, most relation description came from the generic patterns, since the qualia based patterns extract a pre established number of relations, namely, only two isa and consists relation phrases were extracted using Cimiano and Wenderoth 1. Table 6. Comparison between assessment rounds triples and relation phrases. Second round. In the second evaluation round, using the Wiki corpus input, the judges reached an agreement in 6. This time, since the input is much larger than the first one, the number of triples obtained by each system significantly increased. LSOE generated 2,5. Dep. OE extracted 4,2. Re. Verb extracted 5. Figure 2 shows that the systems achieve their better results using a larger input corpus. The precision obtained in this evaluation was 5. LSOE, 4. 9 for Re. Verb, and 2. 7 for Dep. OE. It is interesting to note that Re. Verb performed exceptionally better in this context, obtaining better outcome than Dep. OE. LSOE continues to obtain greater precision than the other two systems, however the difference between LSOEs and Re. Verbs performance was much smaller in this round of evaluation. Figure 2. Precision for Re. Verb, Dep. OE, and LSOE in the second evaluation round. A bar chart of the precision achieved in the second round of evaluation by the systems Re. Verb, Dep. OE, and LSOE. In this round, LSOE obtains better precision than Dep. Andromede 5 Crack. OE and just a little greater precision than Re. Verb. It shows the Dep. OE system with lower precision around 0. Re. Verb system around 0. LSOE with a little higher result than Re. Verb around 0. 5. Regarding the yield metric, LSOE obtained 1,3. Dep. OE obtained 1. Re. Verb 1. 38. 42. Notice that such a high yield measure for the Re. Verb system comes from the sheer amount of relations it extracted from the text considering only those with confidence over 7. Even though Dep. OE extracted around 7. LSOE, given LSOEs high precision, it outperformed Dep. OE in regard to the yield metric. Regarding the lexical syntactic patterns that LSOE used to identify relations, some interesting considerations could be brought. We observed that 2. From this subset, 7. Most of the extracted relations, i. Table 3. From this subset, 7. Table 7 shows the number of relations inside and outside the intersection of the sets of relations extracted by LSOE, Re. Verb, and Dep. OE. In the first round, LSOE learned 1. Re. Verb and Dep. OE. In the second round, LSOE learned 5. Re. Verb and 5. 31 relations not learned by Dep. OE. Observing this data, we realize that LSOE performance can be taken as complementary to the other extractors, since the relations extracted by each method little recur. Table 7. Intersection of relations extracted relations generated by LSOE that were generated or not by Re. Verb and Dep. OE in each evaluation round. Regarding the relation phrases inside the tuples, LSOE learned 8. Table 6. As in the first round, only two isa and consists relation phrases were extracted using Cimiano and Wenderoth 1. In the evaluation set, 3. From those, 2. 6 of the tuples obtained by generic patterns were judged as incorrect and 3. Regarding the relations obtained with Qualia based patterns, 5. Overall perception on the evaluation rounds. Concerning the number of relations that appear in the triples generated by LSOE, as shown in Table 6, there is a similar behavior between the two rounds. That is, regardless the domain and the size of the input corpus, the prototype identified a similar proportion between different relations and extracted triples. These are initial evaluation rounds of the proposed method, and further tests are needed to better explain the disagreement between the two rounds and the three systems. A general analysis of the results indicates the potential of the proposed method. The relationship identified more often by LSOE was the subsumption or instantiation relation is a with 3. Similar relations identified by the other two systems is, are, was, were account for nine instances for the Re. Verb system and 2. Dep. OE system. Note, however, that, especially in the case of Dep. OE, some of these relations may not be regarded as a subsumption or instantiation. For instance, from the sentenceSome notable leaders were Ahmed Ullah., Dep. OE system identified the relation Some notable leaders, were, Ahmed Ullah. The roles of the arguments are reversed in the triple, so that this relation could never be understood as an instantiation. Discussion. Regarding the performance of the systems in the first round, LSOE had much better results, both in precision and yield, than the other two systems. We identify two main reasons for this fact. From our perception of the extractors as a whole, Re. Verb and Dep. OE were designed to work with a much larger and multiple domain data entry. From that, we conclude that the small number of sentences used as input did not allow them to accomplish their best performance. The nature of the texts in the domain specific corpus was formal and academic. Qualia based patterns are very powerful to identify a great number of triples in this kind of sentences, and LSOE may benefit from this. In the second round of evaluation, the other two systems achieved much better performance c. Figure 2. From the 1. LSOE identified 9. Re. Verb and Dep. OE identified 1. 38 and 1.
